Europe's Coldest Cities in Summer. Europe's northernmost city has the continent's coolest summers. No other major city stays anywhere as tepid as ReykjavÃ­k, Iceland, where maximum temperatures average a meagre 12.7 degrees Celsius (54.8 degrees Fahrenheit). That's over five degrees Celsius (10 Â°F) lower than the next coldest city, Leeds.
The prevailing westerly winds, warmed in part by passing over the North Atlantic Drift ocean current, bring precipitation throughout most of the year.

The northern parts of the continent also have this type of climate. Most of Europe receives 500 to 1,500 mm (20 to 60 in) of precipitation per year. Europe vegetation
